A corrosion-resistant and wear-resistant coating is prepared on the inner wall of red copper pipe by centrifugal self propagating melting technology. The morphology of functionally gradient coating on ceramic lining is analyzed by means of SEM, hardness test and electrochemical test, and the hardness, wear resistance and corrosion resistance of the ceramic coating are studied. The results show that the functionally gradient coating is composed of a ceramic lining layer, a metal transition layer and a copper matrix layer. The hardness of the coating is significantly improved and has good resistance to dry wet alternating salt spray corrosion. The wear resistance of the ceramic lining is twice that of the copper matrix.
